Motorists are to be directed to drive on the hard shoulder at peak times to relieve congestion. Sensors in the road will detect jams building up and gantries will flash intructions. The idea is to be tested on a stretch of the M42 near Birmingham.

Sounds like a recipe for chaos if someone breaks down. All the lane changing caused by a stationary vehicle would make the situation much worse than if the hard shoulder wasn't used. And how on earth are emergency vehicles meant to get through? If another lane is needed they sould build one!

Hopefully the same sensors that tell you to use the hard shoulder can be switched to divert traffic off them should something crop up.

I thought I heard something about the hard shoulder being used to ease congestion near junctions by allowing those wishing to exit the motorway at that point to use the hard shoulder to do so when the nearside lane was blocked. It was implied that this would only apply in these circumstances and in certain well known trouble spots.

Sounds completely daft to me.

Too many reasons against to list!

I ride a motorbike - and when it is really jammed up I have strayed onto the hard shoulder. This has resulted in two punctures - serves me right eh?
